The Scope of Existing Substances under K-REACH has been Revised

Under the requirements of MOE Notification 2021-23, the scope of existing substances has been revised. Details are as follows:

  • Hydrates or anhydrates of existing substances are all considered as existing substances;
  • Reaction products composed of two or more components, and each component is an existing substance (these components are difficult to separate by technical means, and the reaction product itself is distributed or used in the market). Under this circumstance, the reaction products are also considered as existing substances; and
  • If an existing substance has two or more configurations, then each specific configuration is regarded as an existing substance;
